hf_papers_index

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Trigger indexing' implies a side effect, but the description does not state whether the operation is asynchronous, what happens if the paper is already indexed, whether it returns a status, or if any permissions are required. This is a significant gap for a mutating action.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence that front-loads the action and resource. Every word earns its place, with no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a simple tool with one parameter and no output schema, so the description is minimally adequate. However, for a trigger operation, it lacks context about what happens after indexing is triggered, any potential delays, or failure modes. Given the low complexity, a score of 3 reflects that it is sufficient but not rich.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes the sole parameter arxiv_id as 'arXiv paper ID', and the tool description mentions 'from arXiv', which is consistent but does not add new meaning. With 100% schema coverage, a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's action: 'Trigger indexing of a paper on Hugging Face from arXiv.' It uses a specific verb ('trigger indexing') and identifies the resource (a paper from arXiv on Hugging Face). This distinguishes it from sibling tools like search, info, and daily, which serve different purposes.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no explicit guidance on when to use this tool versus alternatives. The purpose implies use for indexing, but the description does not mention any exclusions, prerequisites, or compare with sibling tools. This leaves the agent without clear direction on when to choose this over hf_papers_check or hf_papers_info, for example.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
